Ford 6.7L Power Stroke Diesel :: Regen While Towing Heavy With Low Soot Already?
May 31, 2016
Over the holiday weekend I towed my 13k# 5th wheel 180 miles to the campgrounds.
According to my Torque Pro app, soot was around mid 30% when I left home. Upon arrival it had passively dropped to single digits.
After driving unloaded a few times over the weekend, the soot level had gone back up to mid 30s.
While towing home it again had passively dropped back to 1.1% .......... then boom! A regen starts.
After 22 miles it completed and soot had dropped to -13.2%.
So towing heavy, passively burning soot off, exhaust temps in the 700-800 weren't good enough for the system.
It had to start a regen and boost tempts to the 1100-1200 range WHILE TOWING to basically burn off NOTHING.
Not to mention drop my already poor MPG to single digits.
Just venting about what appears to be unnecessary exposure to high temps and wasted fuel.

Now that I have gotten my ScanGauge II to monitor all 4 egt sensor, I am wondering about temperatures while towing, especially how long to idle a hot engine after heavy towing.
I realize all 4 sensors are post turbo (and there is no chance I'm going to drill for an after market pre-turbo sensor). It seems the first one downstream will be the one to watch.
What temperature range we should look for before turning off the engine? IIRC, Ford recommends idling for 3 to 5 minutes, but watching the temp seems a bit more specific.

2002 F350 7.3, MANUAL transmission ZF6.
Bought this truck used for hauling an excavator, and after fixing damn-near everything engine/turbo/and-cooling-system-related ---- it's finally seeing some use.
Just recently started hauling 12,000lb payloads. When I accelerate hard in Low gear, and then shift into 1st and accelerate hard again, I feel the whole truck shuddering. It's like a shimmy-shaking vibration all through the vehicle.
It doesn't happen in higher gears, only when the following conditions are met...
1) Starting from a dead stop
2) 12,000lb payload (heavy)
3) Accelerating hard (Low, First gear)
I would also like to add that I experienced this shuddering vibration very intensely when I put the transfer case in 4wd LOW (front manual hubs left unlocked) and towed 14,000lb up a steep hill in 1st, 2nd, and then 3rd transmission gears.
^^^ By leaving front hubs unlocked and transfer case in 4wd LOW, I was effectively lowering my final drive ratio even more for extra pulling power in 2wd hill-climbing. I don't do this often, only when absolutely necessary. ^^^
I must also add that I do have slightly taller rims/tires than OEM ford WITH the original ford gearing (3.73) so I'm more like 3.51 final drive ratio.

On the way in to work this morning, I get the "Cleaning Exhaust Filter" message. This was great because I still had about 15 minutes of driving left and it usually comes on right when I am pulling into my driveway. As soon as the regen starts, I can smell diesel exhaust/fumes in the cab (this is going 70 mph on the freeway). When the regen was done, the smell went away. Is this normal? I could understand if I was sitting still getting some exhaust in the cab, but moving at full speed everything should be blowing away. This is my 4th or 5th regen and the first time I have noticed it.

I know it seems like everyone's truck tends to have different tolerances when it comes to when it starts and stops regen when it comes to gpl but the last two times my truck has gone into regen it starts at 100% and finishes at 25%. Is it normal to stop regen when it gets to 25% or should it be stopping at 0%. Or could it be that the percentage in my truck is off and it's actually using the gpl to start and Stop? The only thing about that is that forscan says it's supposed to start at 100% which it does so if my percentage is off that would mean it was starting at 75% does it not?

I just had my thermostats replaced in my 6.4, and I'm concerned about the regent process. I read that when the P0128 code is thrown, truck will not go into regen. Is this true? How can I manually start the regen process?

I purchased a 2016 f350 XLT 6.7 it's basically two weeks old with roughly 1500 the horsepower and fuel economy is incredible however it's developed a terrible shake during regen. It occurs every time regen and shifting down isn't working. Hard to believe a two week old truck has to go back to the dealer and from what I'm reading it sounds like they're not solving it.

Is there an alert setting to signal when a regen starts? My engine stumbles badly a few seconds after a regen starts. The dealer hasn't found the problem. Right now I just keep an eye on the soot level gauge.

Last week I picked up a 2016 F-350 with the 6.7 diesel. Since then I have put about 4500 miles on it and gone through 2 or 3 regenerations. About half the miles were empty, half were with about 1500lbs of cargo in the bed. Mostly interstate driving at about 70mph.
However, every time the "cleaning exhaust filter" message comes on in the screen it feels like the truck looses all power for a second. The first time I was going up hill with cruise control set at 70 and it felt like stomping the brakes then hitting the gas all within a second maybe.

Last year while towing my fifth wheel to the North Rim of the Grand Canyon my oil temp went to 260 degrees several times. The outside temps were 95 degrees at the start and it is a long steep climb with a heavy load. Each time I pulled over for a bit, as I couldn't remember at what temp that plastic thing inside the oil filter melted. Each time it cooled off fairly quickly but it really stressed me out. So how hot can the oil get. I am using Rotella T-6 and my temp different is only 12-15 unloaded. Could I allow 280 for 15 minutes or so?

My dad recently bought 2006 6.0. He has had it about 2 and half months. Has the egr delete kit installed. The truck has ran great. Up until Wednesday the 3rd. My dad headed to Ut to pick up our new quads. While heading up a small grade with empty trailer in tow. Truck went to limp mode, fan kicked on, orange wrench came on on dash board. He pulled over let her cool down turned her off.
Checked fluids Then started her back up and she was fine. That has happened 3 times. Now he is on his way back (tow haul mode turned on) and it is doing it again. She hasn't went into limp mode yet. As soon as the fan kicks in my dad pulls over immediately and puts it in park. And lets her cool down checks fluids. This issue only happens mid way up a grade. So my question is...... What is causing this? How do we fix her and make her a happy truck again.

I have a 05 6.0l that started over heating while towing recently. In 2012 i did egr delete, oil cooler, stc fitting, and coolant filter. I recently changed radiator and tstat think that was the problem due to small leak in radiator, but still towing about a 4-5k load temps rise to over heat while towing. What to look for next. Also fan seems to be work properly I monitor fan speed etc., and tft on my scangauge.

I have an 06 F-250 with 122,000 miles. When driving empty at 70-75 mph the coolant temp runs 194-200 and the oil temp 5 to 10 degrees higher at the most. When I pull my travel trailer the coolant temperature will start to steadily climb then abruptly drop down under 200. I have seen the coolant temperature pass the oil temperature when this happens.
The last time I pulled the trailer I was driving at 60 mph and the coolant temperature climbed to 220 then dropped to 196. A few miles later it climbed to 230 then dropped to 200. While the temperature was climbing I slowed to about 45 mph. As it was dropping I accelerated and the temperature continued to drop.
I have flushed the cooling system, replaced the thermostat and cap with no improvement.
The pickup has an SCT tuner set to street 1 and I was told by the previous owner that the egr was deleted, but the stock egr cooler is in place. It is possible that a plug was put in. I pulled the egr valve and the carbon coating on it is gooey like it has been wet.

Just looking for comments on using the cruise control while towing? and what's the recommended weight for using the tow haul mode. The enclosed trailer I have is about 3300 lbs. taking it across the country empty. 2004 6 liter.

I have a 2006 f250 bulletproofed for about 5 years now with no problems other than normal wear and tear. I had the factory water pump go out a couple months ago so I decided to go with the bulletproof diesel pump for piece of mind now I do tow anywhere from 8K-15K about once a week with custom Gearhead tunes using SCT.
While I was changing water pump, I ordered low temp thermostat figured it would work with towing temps even though they weren't that bad to begin with my deltas always around 10-128.. Now i am seeing signs of puking out degas bottle, I replaced cap seems to work a little the truck doesn't puke unloaded unless i really get down on it.
I noticed the other day while towing I was cruising with TC locked in at around 55 mph and i watched my EOT 210* and ECT 205*, the n ECT started climbing up followed by EOT then at ECT 222* fan came on ECT finally hit 234* and started dropping fast while EOT never got over 226*. ECT would level out at 188* go back up to 205* and stay there for awhile and do it all over again...
What is going on. I've talked to a could mechanics and they aren't confident its the HG..

I was towing the 5er (about 15000#), across Southern Mn and SD today going right into a 20-25 mph wind in upper 90 temps, saw 228 on the oil temp and 199 on the tranny temp. When tow need to see for warmest temps and at what point you start to get concerned...

Took my first camping with 2012 King Ranch F350 and 37 feet Challenger 12k fifth wheel trailer over the weekend.
I noticed there is lot of transmission slips in first gear. Once it enters 2nd gear, no more slips.
My previous Chev 2008 2500HD diesel didn't slip much with same trailer.
Is this normal for this F350? My rear ratio is 3.55. No slips without hauling.
Maybe I need to ask dealer to check 1st gear towing?

I've got about 1100 miles on my new truck now and I will be heading to S.D in a week or so towing my car hauler with FJ40 on top and camping gear. About 10 000 pds.
Would it be wise to dump the factory oil and go with 5w40 Rotella? It has been getting really hot here the last two weeks and its only getting hotter as I drive south.

I was towing a fairly heavy trailer yesterday (around 10k) and laying into the throttle to gain some speed before a big hill when I completely lost power. It slowed me down to about 10 MPH.
I was able to drive home at very slow speeds and the only way to get over 10 MPH (only up to about 20MPH was to very lightly accelerate up to speed. Any hard acceleration and it cut me off to 10 MPH. No warning lights of any kind going off...
Truck has a Hypertech Max Energy programmer on stage 2.

2013 6.7L F-250
The owner's manual recommends idling for a period of time after towing to allow the turbo to cool somewhat. After towing a 10K lb travel trailer in the mountains, what temperature should i shoot for as sufficiently cooled? When towing the oil to averages about 210-215-F. Normal operating temp is about 190F.

For the last couple months when not towing I take the front tires to 65 psi and the rears to 50 psi. It gives me the warning light which I click OK to every time I start it. This weekend I put everything back to 80 psi getting ready to tow and I can't get the warning light to go out anymore. I double checked my pressure to make sure everything was OK and it was. I will be taking it in unless someone knows a reset or something else to check out before I do.
